Installation methods and steps




There are different methods to install RHEL 7.2 on your server, depending on your preferences and availability of resources. The most common methods are:



  • DVD/USB: You can use a DVD or a USB flash drive that contains the RHEL 7.2 ISO image to boot your system and start the installation process. You can download the ISO image from the Red Hat Customer Portal or the Red Hat Developer Program, depending on your subscription type. You can also use tools such as dd or Rufus to create a bootable DVD or USB from the ISO image.

You need to configure a PXE server that provides the RHEL 7.2 boot image and installation source, as well as a DHCP server that assigns an IP address to your system. You can follow the instructions in the official documentation to set up a PXE server for RHEL 7.2.



  • Kickstart: You can use a Kickstart file to automate the installation process by specifying the configuration options in advance. A Kickstart file is a plain text file that contains commands and parameters that are normally entered during the interactive installation process. You can create a Kickstart file manually or use tools such as Anaconda or system-config-kickstart to generate one. You can also use tools such as Cobbler or Satellite to manage multiple Kickstart installations across your network.



Anaconda: You can use Anaconda, the default graphical installer for RHEL 7.2, to perform an interactive installation process by following the prompts and selecting the options on the screen. Anaconda allows you to customize various aspects of the installation, such as language, keyboard layout, time zone, partitioning scheme, software selection, root password, user cre
